Above all else, remember that Islam stands for Peace, Muslims dislike Zionism but love Jews, it has not yet been proven that the assailant was an Arab Muslim, most Muslims are not terrorists, despair in the Palestinian territories leads to violence, Israel is building settlements in the Occupied West Bank, and can't we all just live in peace? Whew, that's a lot of buzzwords and stupid clichès for a single sentence but if you have more, please add them.
I very seldom give thought to Milan, Italy but I believe that the Jewish community there is rather small. However, it's not small enough to avoid the attention of those lovely and downtrodden Arabs.
